Table - best surf conditions forecast for Jaconé over the next 16 days.
Alright, let’s talk about Jaconé. The first few days are a total wash. But once the wind straightens out, there’s some fun to be had.
Wednesday morning is a mess – onshore wind and poor surf. That goes right through Wednesday afternoon. You gotta wait until Thursday morning, July 9, for the switch. That morning it goes glassy, clear skies, and a clean 5 ft swell from the SSW at 9 seconds, moderate energy (602). That’s a nice session for an intermediate, super clean. Thursday afternoon gets a light cross-onshore, so it drops off.
Friday morning July 10 is another good one. Swell drops to 3 ft but it’s from the SE with a long 14-second period, light offshore NE wind. Clean, lined-up waves with moderate energy (478). Best for a point or reef. Friday afternoon gets a little crossed up.
Saturday and Sunday mornings have waves but the wind isn’t perfect. Saturday morning is cross-onshore with 3 ft SE swell. It’s just okay.
The standout is Sunday July 12 morning. You’ve got 4 ft from the S, 10-second period, and cross-offshore east wind – clean. The combined energy is a solid 600. This is going to produce good, well-shaped waves for an intermediate. Crowds are possible, so get out early.
Monday July 13 morning looks good too with 5 ft S swell, 12-second period, cross-off wind, and high energy (811), but the light rain might put a damper on it. The afternoon goes onshore and garbage.
After a rough midweek, Thursday July 16 morning is another gem. 5 ft from the SSE, 11-second period, offshore NE wind, very clean, energy at 529. That’s more quality glassy surf.
The weekend of July 18-19 is smaller – waist-high from the east with short periods under 8 seconds. Clean but ordinary. Good for a longboard.
Into the next week, July 20 and 21 stay clean and offshore but the swell is weak and short period. Energy drops below 200. There’s a little blip on Thursday July 23 morning – 3 ft from the east, 8-second period, glassy offshore wind, energy 221. Surfable but nothing special.
Bottom line: Thursday July 9, Sunday July 12, and Thursday July 16 are your best shots for clean, intermediate-friendly waves.
Water temp is about 74°, right on average for this time of year – nothing unusual.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
